This project comes from the "Monitoring and blocking the bittorrent monitoring spies" study (performed between 2014 and 2018), which took some intriguing directions, the public part of the study is here : https://gist.github.com/Ayms/79bdfc6ba747fb49503d , an unexpected side effect is to unveal how to deanonymize peers that are using a VPN, which can also be combined to deanonymize them when they are using/multiplying other methods to hide and paradoxically the more they try to hide the better they can get caught
That's not theoretical/academic work and has been tested, this self financed project goes to the organization that would fund this work, the complete study corresponds to the undisclosed parts of the public study, contact: PGP Key fingerprint (aymeric peersm com): 65EF AE3D 973F D36A AB25 1225 2A1D 7B34 2627 AC39
